FMY-98

Overview: FMY-98 FM Band Directional Yagi Antenna

The FMY-98 is a high-gain, professional-grade Directional Yagi-Uda Antenna specifically engineered for the 88–108 MHz FM broadcast band. Designed to deliver superior directional performance for long-range transmission, spectrum monitoring, and point-to-point links, this antenna represents a fusion of innovative mechanical design and elite RF engineering. With a peak gain of 10 dBi, the FMY-98 provides the necessary signal concentration and interference rejection required for critical mission-profiles in the VHF spectrum.

Hardened Construction & Design

Strategic materials for persistent performance in extreme environments. The FMY-98 is constructed using high-quality 6063T6 ultra-corrosion-resistant architectural aluminum alloy. The use of specialized metal castings for the element-to-boom junctions ensures structural rigidity and long-term durability. For safety and signal purity, the antenna is designed to withstand severe environmental stress, and all mounting hardware is fabricated from marine-grade stainless steel to prevent corrosion in humid or coastal theaters.

Operational Efficiency & Field Readiness

Versatile polarization and modular architecture for rapid deployment. A key feature of the FMY-98 is its specialized mounting hardware, which permits the antenna to be installed in either Horizontal or Vertical polarization. This flexibility is essential for matching the polarization of the target network or for mitigating local multipath interference. The antenna is factory-tuned and requires zero field adjustments. For streamlined logistics, it is supplied with elements removed from the boom, allowing for a compact shipping profile, yet it can be rapidly assembled at the site using simple hand tools.

Detailed Technical Features
